Roxie and Skyla are pretty cool! Roxie's in a band and she's really spunky! Skyla is really fun and has awesome gym puzzles!
My least favorite, I'd have to say Marlon. For the final gym leader, he was just too easy. I guess that fits his laid-back personality, but I wish he put up more of a challenge. I mean, I like his personality, and his gym puzzle is neat, but as an actual gym leader, I don't care for him that much.
